A command for diagnosing Azure sign-in and credential problems. Azure is Microsoft's cloud platform, and the guide covers user, device-code, service-principal, and managed-identity sign-in.

Use it to check the current Azure account, start an interactive or device-code login, sign in with a service principal, or use a managed identity.

It explains why Azure commands fail and which type of login fits interactive use, remote machines, automation, or Azure-hosted services.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/charris-msft/azure-plugin

Per session 10 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 907 The whole file, excluding the scripts and references it only reads on demand.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00010	$0.00907
Opus 5	$0.00005	$0.00453
Sonnet 5	$0.00002	$0.00181
Haiku 4.5	$0.00001	$0.00091

Security

Grade A, and why

auth scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Azure Authentication Help Command

Diagnose and resolve Azure authentication issues.

Diagnostic Steps

1. Check Current Authentication Status

az account show 2>&1

Analyze the output:

If successful: Show current account and subscription
If "Please run 'az login'": User needs to authenticate
If error: Diagnose specific issue

2. Common Authentication Scenarios

Interactive Login (Browser)

For users with browser access:

az login

Device Code Login (No Browser)

For headless or remote environments:

az login --use-device-code

Instruct user to:

Open https://microsoft.com/devicelogin
Enter the displayed code
Complete authentication in browser

Service Principal Login

For automated/CI scenarios:

az login --service-principal \
  --username <app-id> \
  --password <client-secret> \
  --tenant <tenant-id>

Required information:

Application (client) ID
Client secret or certificate
Tenant ID

Managed Identity Login

For Azure-hosted environments (VMs, App Service, etc.):

az login --identity

For user-assigned managed identity:

az login --identity --username <managed-identity-client-id>

3. Token Management

Check Token Expiration

az account get-access-token --query "expiresOn" -o tsv

If token is expired or expiring soon:

az account get-access-token --resource https://management.azure.com/

Clear Cached Credentials

If experiencing stale credential issues:

az account clear
az login

4. Subscription Management

List All Subscriptions

az account list --output table

Switch Subscription

az account set --subscription "<name-or-id>"

Verify Current Subscription

az account show --query "{Name:name, ID:id, State:state}" -o table

Common Issues and Solutions

Issue: "AADSTS50076" - MFA Required

Cause: Multi-factor authentication is required but not completed.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
